Creating a Storage Pool on a RAID Enclosure

Important:
  • The Mode switch on the RAID enclosure must be set to Software Control mode. For details, see the enclosure's hardware user guide.

  • The RAID enclosure must not contain any existing RAID groups.

Warning:

To prevent errors or data loss, do not change the enclosure Mode switch from Software Control to any other mode while the enclosure is connected to the NAS.
